Maintenance Recommendations
** Under No Circumstances should anyone enter the
water while a aerator is operating. **
** Please keep the original box for maintenance ship-
ping. **
The following maintenance procedures can be uti-
lized to ensure many years of quality performance
from your Kasco aerator and reduce the need for more
costly repair work.
PROPER INSTALLATION: Proper installation of
Kasco equipment will include a power source with
ground fault interruption. For aerator models, the
C-85 or C-95 (240/208V) included with the unit have
built-in ground fault interruption that is sufficient.
Ground fault interrupters are a safety feature that can
also alert you to electrical leaks in the equipment. It is
extremely important to test the GFI upon installation,
each reinstallation, and monthly thereafter to ensure
proper operation. If you have repeat, consistent trips
on your ground fault, the equipment should be discon-
nected and removed from the water. The power cord
should be inspected for damage and you should call
Kasco Marine at 715-262-4488 for further instructions
or email Kasco at [email protected].
OBSERVATION: Operating equipment should be
observed on a regular basis (daily, if possible) for any
reduction or variation in performance. If a change in
performance is observed, the equipment should be dis-
connected from power and inspected for any material
that may have clogged the system or wrapped around
the shaft of the motor, especially plastic bags and fish-
ing line. Even though Kasco Aerators are among the
most clog-resistant on the market, it is impossible to
protect against all items that can clog equipment and
still maintain a flow of water. These materials can be
very damaging to the equipment under continued op-
eration and must be removed as soon as possible. AL-
WAYS UNPLUG THE UNIT BEFORE ATTEMPT-
ING TO REMOVE CLOGS.
WINTER STORAGE: In regions where there is sig-
nificant freezing in the wintertime, the aerators should
be removed from the water to protect them from the
expansion pressure of the ice. In many areas, aerators
will keep some amount of ice open through the winter.
However, when the water is thrust into the air, it is
exposed to the colder air temperatures longer and can
actually make ice thicker on the pond/lake. Storage
over winter is best in a location that is out of the sun
and cool, but above 32 O F. When storing units during the
offseason, it is important to store them upside down if they
are going to be sitting for long periods of time. Units that
sit upright on a shelf for many months, or even years have a
greater likelihood of seals drying out. Storing upside down
will ensure oil is lubricating the seals and prevent drying.
CLEANING: Aerators should be removed from the
water at least once per year (at the end of the season
in cold climates) to clean the exterior of the system,
especially the stainless steel motor housing (can). The
motor housing is the surface that dissipates heat into
the water and any algae, calcium, etc. build-up will be-
come an insulator that blocks heat transfer. In warmer
regions it is recommended that the motor is removed
and cleaned at least two to three times per year de-
pending on conditions. In most cases a power washer
will be sufficient if the unit and algae are still wet.
SEAL AND OIL REPLACEMENT: This is a sealed
motor assembly and seals will wear out over time
(similar to brake pads on a car). Replacement of the
seals and a change of oil after three years may add
longevity to the operation of the motor, saving you
the cost of more expensive repairs. In warmer cli-
mates where the aerator runs most or all of the year,
it is a good idea to replace seals more regularly than
you would need to in colder climates where the unit is
removed from the water for several months.
ZINC ANODE: A Sacrificial Zinc Anode is supplied
on the shaft of all 8400JF, 3.1JF, and 5.1JF Model
aerators for protection of the equipment from corro-
sion and electrolysis. The zinc anode should be up-
dated (replaced) if reduced to half the original size or
if white in color. Corrosion from electrolysis is more
commonly associated with saltwater or brackish water,
but as a matter of precaution, it is important to periodi-
cally check the zinc anode in all installations (at least
every two to three months).
Seal replacement and all other repair services should
be performed by Kasco Marine or a Kasco trained
Authorized Repair Center. Any alterations or changes
made to Kasco units by an unauthorized source will
void the warranty. This includes tampering with the
unit, power cord, and/or control box. Please contact
